HERMANN BENSMANN, OF MINSTER, OHIO.

WINDMILI...

SPECIFICATION forming part of Letters Patent No. 293,704, dated February 19, 1884.

Application filed August 17, 1883. (No model.) I

To ail wiz/m t may concern:

Beit known that I, HERMANN BnNsMANN, a citizen of the United States, residing at Minster, in the county of Auglaize and State of Ohio, have invented certain new and useful Improvementsin l/Vindmills, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to improvements in windmills, and it consists in the construction and novel arrangement of the same, all as will be hereinafter more fully explained, and particularly pointed out in the claims appended.

The annexed drawings, to which reference is made, fully illustrate my invention, in whichproved windmill.

Figure 1 represents a side view of my im- Fig. 2 is a sectional view of the wind-wheel, and Figs. 3 and 4 are other detail views, and Fig. 5 is a perspective View of arm D.

Referring by letter to the accompanying drawings, A is the platform, which is elevated in the usual manner, and provided with the stationary table A', that is supported upon legs or posts c c, secured to the platform,

B designates a U-shaped framethe crossbar c of which is provided with a downwardlyprojecting tube, a", which is screw/threaded to receive a nut, a3, whereby the U-shaped frame is secured to thestationary table. Said crossbar has secured toits under side a plate,`b, that rests on the stationary table and revolves thereon, carrying the said frame and mill therewith.

B indicates the vertical shaft that extends from the ground up through the tube c2, and is provided with a pinion, b', at its upper end, that engages' a smilar pinion, b2, secured to a horizontal shaft, b3, that has its bearings' in the upright arms of the U-shaped frame. rlhe forward end of the horizontal shaft b3 is provided with a gear-wheel, C, which meshes with a pinion, c, on a horizontal shaft, c', arranged above the shaft b3, and having its bearings in the vertical arms of the U -shaped frame aforesaid.

' C represents the wind-wheel, the hub d of which is provided with a rearwardly-projecting tube, d', on which the pinion c is secured, and between the hub and said pinion straddles an arm, d2, that is secured at its upper end to the vertical front arm of the U-shaped frame, as shown in the ldrawings, which arm secures the wheel to the frame and at the same time allows said wheel to revolve.

On the outer end of the wheel-shaft c is rigidly secured a disk, e, having extending therefrom radial arms cecc, the outer ends of which engage eyese2 e2 on the rods e3 e3, which latter are provided with eyes f 'f at each end,

to engage studs f f on the outer edge of the wheel-blades fzfz, which rods c3 e3 connect all the blades to oneanother. The inner ends of the blades are provided withjj ournals that have their bearings in the hub of the wheel, and the outer ends of the blades have similar journals that have their bearing in the rim g of said wheel, and the rim and hub are connected to one another by radial spokes g2 g2. rlhe shaft c is provided with a longitudinal groove, lz, that extends from the front vertical arm of the U-shaped frame to the outer end of the shaft, in which groove plays a stud or pin, h, that is secured to the hub of the wheel.

On the shaft c', between the two vertical arms of the U -shaped frame, is rigidly secured a collar, i, and between this collar and the rear arm of the U-shaped frame and encircling said shaft c', is a coil-spring, i', that has its end bearings against said collar and the rear arm aforesaid. y

D indicates a right-angular bar, the vertical portion k of which is bolted to the inner face of the front arm of the U-shaped frame, and the horizontal portion' 7c -is provided with an eye, Z, to which is pivoted one end of a slotted bar, Z, which is arranged in front of the collar on the shaft c', and said shaft passes through and works within the slot of said bar Z. The opposite end of the bar Z to that of the pivoted end is provided with perfor-ations m m, to which is connected one end of a rod, m', while the opposite end of .said rod is connected to a wing, E, that is hinged at its lower end to bar a, secured to the vaneE. The rod mlis connected by its hooked end a" to one of the perforations in the arm or bar Z while its opposite hooked end is connected to an eye, p, in the end of a bar, p', that is secured to the vane E', as shown. rlhe forwardend of said vane is pivoted bya vertical bolt, p2, between IOO the upper and lower arms, r o', of a U-shapcd bracket, s, which bracket is secured to the rear vertical arm of the U-shaped frame.

F indicates a bar secured at its rear end to the vane E', and provided with an eye, s', in its forward end, to which is connected one end of a rod, t, while the opposite end, t', of said rod connects with the upper end of a vertical rod, 1v, the end t? of which is bent at right angles to the vertical rod u, which rod passes through the tube and extends to the ground, and its lower end is also bent at right angles to said vertical rod fw, and serves as a lever to operate the vane through thc medium of the connecting-rod i.

It will be observed that the operation of my 4windmill is automatic, and that the speed can be regulated evenly.v Should the wind be too strong, the wing E is struck by the same and forced rearwardly, and by means of the rod m', connected thereto, the bar Z is carried therewith, and by the same pressing upon the collar of the wheel-shaft said shaft is drawn rearwardly, and thus through the medium of the radial arms c c c c closes the blades of the wind-wheel, and when the wing is relieved from pressure the spring on the wheel-shaft forces the blades out to their normal position, and at the same time the vane E is also thrown in and out of operation with the wind through the medium of the rod m2, which is connected at one end to the slotted arm l and at the opposite end to the bar p, secured to the vane E.

Vhen it is desired to use the device for running machinery where a regular speed is required, the connecting-rod m2 is to be detached from the vane E and bar Z, and the vane is thrown in and out of the wind by means of the vertical rod zu through its connecting-rod Having described my i11vention,wl1at I claim,

and desire to secure by Letters Iatent, is-

l. The combination, in a windmill, of the wheel-bladesf2 f2, connected to one another by the rods e c, having eyes in each cnd to engage the studsf f, the arms c c, secured to he rods c" c", and disk e on the end of the shaft c', which latter is provided with the groove 71 to engage the pin h in the hub of the wheel G, of the pivoted slotted bar Z', shaft c', spring i', connectingrods m m2 t, gear-wheel C, pinions c b b2, wing E, vane E', U-shapcd frame B, and stationary table A, as shown and dcscribed. Y

2. The combination,in a windmill, of the U- shaped frame B, provided with bearings for thehorizontal shafts c b" of the stationary .table, supported upon the posts a (t, the vertical operating-rod w, bent at its upper and lower ends at right angles thereto, of the connecting-rods, gear-wheels, pinions c b D, slotted bar Z, shaft c', spring i', wing E, vane E', and wind-wheel C', constructed as described, the whole as shown and set forth.

In testimony whereof I afiix my signature in presence of two witnesses.
